Bawdsey
Bawdsey is a village and civil parish in Suffolk, eastern England. Located on the other side of the river Deben from Felixstowe, it had an estimated population of 340 in 2007, reducing to 276 at the Census 2011. Bawdsey Manor is notable as the place where radar research took place early in World War II, before moving to Worth Matravers near Swanage in May 1940, and from there to Malvern, Worcestershire in 1942. Bawdsey had both Chain Home and Chain Home Low early warning radar stations during World War II. The World War Two defences constructed around Bawdsey Point have been documented. They included a number of pillboxes, landmines and flame fougasse installations. The beaches were protected with extensive barriers of scaffolding. Bawdsey Cliff SSSI Bawdsey Cliff is a Site of Special Scientific Interest noted for its geological importance. It is in size and provides over of exposed Gelasian (early Pleistocene) Red Crag, the most significant exposure of Red Crag in Engla ...

Bawdsey Manor
Bawdsey Manor stands at a prominent position at the mouth of the River Deben close to the village of Bawdsey in Suffolk, England, about northeast of London. Built in 1886, it was enlarged in 1895 as the principal residence of Sir William Cuthbert Quilter. Requisitioned by the Devonshire Regiment during World War I and having been returned to the Quilter family after the war, it was purchased by the Air Ministry for £24,000 in 1936 to establish a new research station for developing the Chain Home RDF (radar) system. RAF Bawdsey was a base through the Cold War until the 1990s. The manor is now used by PGL for courses and children's holidays. There is a small museum in the radar transmitter block. History Quilter period: 1886 to 1936 Bawdsey Manor was built in 1886 and enlarged in 1895 by William Quilter who was an art collector, one of the founders of the National Telephone Company, and was Liberal/Liberal Unionist Member of Parliament for Sudbury. He established a steam- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain Home
Chain Home, or CH for short, was the codename for the ring of coastal Early Warning radar stations built by the Royal Air Force (RAF) before and during the Second World War to detect and track aircraft. Initially known as RDF, and given the official name Air Ministry Experimental Station Type 1 (AMES Type 1) in 1940, the radar units themselves were also known as Chain Home for most of their life. Chain Home was the first early warning radar network in the world, and the first military radar system to reach operational status. Its effect on the outcome of the war made it one of the most powerful weapons of what is today known as the "Wizard War". In late 1934, the Tizard Committee asked radio expert Robert Watson-Watt to comment on the repeated claims of radio death rays and reports suggesting Germany had built some sort of radio weapon. His assistant, Arnold Wilkins, demonstrated that a death ray was impossible but suggested radio could be used for long-range detection. In Febr ...

Chain Home Low
Chain Home Low (CHL) was the name of a British early warning radar system operated by the RAF during World War II. The name refers to CHL's ability to detect aircraft flying at altitudes below the capabilities of the original Chain Home (CH) radars, where most CHL radars were co-located. CHL could reliably detect aircraft flying as low as . The official name was AMES Type 2, referring to the Air Ministry Experimental Station at Bawdsey Manor where it was developed, but this name was almost never used in practice. The system had originally been developed by the British Army's research group, also based at Bawdsey, as a system for detecting enemy shipping in the English Channel. It was built using the electronics being developed for the Airborne Interception radar systems, which worked on the 1.5 m band. This high-frequency (200 MHz), for the era, allowed it to use smaller antennas that could be swung back and forth to look for returns, in contrast to the enormous fixed anten ...

Telecommunications Research Establishment
The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man." The name was changed to Radar Research Establishment in 1953, and again to the Royal Radar Establishment in 1957. This article covers the precursor organizations and the Telecommunications Research Establishment up to the time of the name change. The later work at the site is described in the separate article about RRE. History TRE is best known for work on defensive and offensive radar. TRE also made substantial contributions to radio-navigation and to jamming enemy radio-navigation. Rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Felixstowe
Felixstowe ( ) is a port town in Suffolk, England. The estimated population in 2017 was 24,521. The Port of Felixstowe is the largest container port in the United Kingdom. Felixstowe is approximately 116km (72 miles) northeast of London. History The town is named after Felix of Burgundy, a saint and the first bishop of the East Angles in the seventh century. The old Felixstowe hamlet was centred on a pub and church, having stood on the site since long before the Norman conquest of England. The early history of Felixstowe, including its Roman, Anglo-Saxon, Norman and medieval defences, is told under the name of Walton, because the name Felixstowe was given retrospectively, during the 13th century, to a place which had expanded to a form beyond the boundaries of Walton alone. In the Doomsday book, for instance, only Walton is shown, and not Felixstowe, which at the time held little more than a few houses scattered over the cliff tops. Walton was a settlement on the River Orwell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Crag Formation
The Red Crag Formation is a geological formation in England. It outcrops in south-eastern Suffolk and north-eastern Essex. The name derives from its iron-stained reddish colour and ''crag'' which is an East Anglian word for shells. It is part of the Crag Group, a series of notably marine strata which belong to a period when Britain was connected to continental Europe by the Weald–Artois Anticline, and the area in which the Crag Group was deposited was a tidally dominated marine bay. This bay would have been subjected to enlargement and contraction brought about by Marine transgression, transgressions and Marine regression, regressions driven by the 40,000-year Milankovitch cycles. The sediment in the outcrops mainly consists of coarse-grained and shelly sands that were deposited in sand waves (megaripples) that migrated parallel to the shore in a south-westward direction. The most common fossils are bivalves and gastropods that were often worn by the abrasive environment. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Landmines
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. Seventy-eight countries are contaminated with land mines and 15,000–20,000 people are killed every year while many more are injured. Approximately 80% of land mine casualties are civilians, with children as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Villages In Suffolk
A village is a clustered human settlement or community, larger than a hamlet but smaller than a town (although the word is often used to describe both hamlets and smaller towns), with a population typically ranging from a few hundred to a few thousand. Though villages are often located in rural areas, the term urban village is also applied to certain urban neighborhoods. Villages are normally permanent, with fixed dwellings; however, transient villages can occur. Further, the dwellings of a village are fairly close to one another, not scattered broadly over the landscape, as a dispersed settlement. In the past, villages were a usual form of community for societies that practice subsistence agriculture, and also for some non-agricultural societies. In Great Britain, a hamlet earned the right to be called a village when it built a church. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deben Estuary
Deben Estuary is a biological Site of Special Scientific Interest (SSSI) covering the River Deben and its banks from its mouth north of Felixstowe to Woodbridge in Suffolk. It is a Ramsar internationally important wetland site and a Special Protection Area under the European Union Directive on the Conservation of Wild Birds. It is also in the Suffolk Coast and Heaths Area of Outstanding Natural Beauty. It partly overlaps two geological SSSIs, Ferry Cliff, Sutton and Ramsholt Cliff. The site has been designated an SSSI for its overwintering waders and wildfowl, and for its diverse saltmarshes. It has internationally important overwintering redshanks and nationally important numbers of dark-bellied brent geese, shelducks and black-tailed godwit The black-tailed godwit (''Limosa limosa'') is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. It is a member of the godwit genus, ''Limosa''. There are four subspecies, all with orange head, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Gelasian
The Gelasian is an age (geology), age in the international geologic timescale or a stage (stratigraphy), stage in chronostratigraphy, being the earliest or lowest subdivision of the Quaternary Period/System and Pleistocene Epoch/Series. It spans the time between 2.58 annum, Ma (million years ago) and 1.80 Ma. It follows the Piacenzian Stage (part of the Pliocene) and is followed by the Calabrian (stage), Calabrian Stage. Definition The Gelasian was introduced in the geologic timescale in 1998.Rio, D., Sprovieri, R., Castradori, D., Di Stefano, E"The Gelasian Stage (Upper Pliocene): A new unit of the global standard chronostratigraphic scale" ''Episodes (journal), Episodes'', Vol. 21, No. 1, March 1998. pp 82-87. Retrieved March 18, 2020. It is named after the Sicily, Sicilian city of Gela in the south of the island. In 2009 it was moved from the Pliocene to the Pleistocene so that the geologic time scale would be more consistent with the key changes in Earth's climate, oceans, and ...
